Innovative technology for cyanobacterial bloom controlInovativna tehnologija kontrole cvetenja cianobakterij



What was our contribution to the implementation of the EU environmental policy?

Facts• Eutrophication of water bodies can result in

(toxic)cyanobacterial (CB) blooms

• Consequences of massive CB blooms:

• disruption of ecosystem balance

• Hazardous toxins, unpleasant odour and

taste of water

Targeted EU policies implementation

• Bathing Water Directive 2006/7/EC

• Monitoring, early warning, actions to prevent

exposures in case of CB occurrence

• Water Framework Directive 2000/60/EC

• Achieve at least good chemical and ecological status

of waters by 2015

Goals

Construction of solar powered vessel with set of instruments for:

• Detection of CB and algae

• Remote control & data transmission & interpretation

• In-lake control of CB and cyanotoxins(electrooxidation)

Expected effects of electrochemical oxidation:

- Approx. 90% decrease of CB

- Absence of microcystins

- Positive effect on lake biodiversity

Gaining interest for the adoption of the technology

Project application scheme



How to prevent unwanted cyanobacterial blooms?

In-lake methods

Internal (re)loading control

(sediment)

Inflow nutrient management

Catchment nutrient management

monitoring

of efficiency of mitigation/treatment activities

Project focus



Project enabled gaining new skills and numerous technological improvements

• Improved water ecology skills

• Phytoplankton monitoring

• Algae taxonomy

• Finished technical improvements

• multifunctional unmanned solar powered

water platforms

• solar powered docking stations

• Performed extensive on-line monitoring of

water bodies

• Gained new insights into the effects of

electrochemical oxidation in different steps of

water treatment

LIFE project enabled development of several innovative technological solutionsAchievements are applicable in research and various water management activities!

Water flow regulation withsmart valves; preventing celldeformations.

Developed software combining automaticnavigation, water measurements, treatment andsampling

Information system for remote control,transfer and presentation of measured data

On-line measuring chamberwith integrated electronicwith simultaneous readingfrom 5 sensors

Electrolytic cell with anodeoxidation with adjustablecurrent and self cleaningcapacity preserving electrodesustainability

Automatic dockingwith robotic visionand fuzzy logiccontroller

Automatic samplerwith integratedelectronics andwinch with a hosefor deep watersamples

Independently applicable parts of the robotic vessel



Anode oxidation (Advanced Oxidation Process) : approach used for in-lake cyanobacteria growth control and cyanotoxins inactivation in LIFE Stop CyanoBloom project

Advanced oxidation process (AOP):production of hydroxyl radicals (●OH) directly from water in electrolytic cell

Boron doped diamond electrodes:- High oxygen over potential- In situ production of

oxidants- High ●OH production rate- Production of physisorbed

radicals

Advantages:- ●OH are short-lived- Effects after short reaction times

Wastewater treatment:

- Ship ballast water

- High strength wastewater (leachate, industrial outflows)

- Removal of micropollutants

- Improving biodegradability

Technological water, drinking water preparation:

- Disinfection

- Detoxification

In-lake water treatment:

- Selective action on phytoplankton

Toxins inactivation / degradation

Surface of diamond electrode with boron doping

Various application options of anode oxidation.



Arhel: technological improvements on electrolytic cell to achieve efficient anode oxidation

Solved questions concerning: Achieving high contact of pollutant with ●OH Constant/ adjustable power supply of electrolytic cell in different water conditions Improving durability of electrodes and reducing the need of maintenance Reduced use of energy, operation using solar power Automated control and management

Electrochemical oxidation has been tested in several applications
